These types of coolers aren't really meant for long-term storage, but for chilling wine. Yes, they can keep wines from hitting extremes if you don't have a/c but really meant as a place to keep wines you are drinking, not keeping. If you are keeping both reds and whites in it, pick a temperature in the low 50s, and before drinking take reds out to warm and if you want whiltes colder, pop them in the fridge.
